Research
Research is not a department. It is the company.
SONA is building a permanent research institution where scientific discovery continuously produces the next generation of medical technology.

Active programs
What we are working on.
- PR01
Non-contact physiological measurement
Estimating cardiac, respiratory, and thermal signals without contact, and characterizing the conditions under which those estimates remain reliable.
- PR02
Individualized baseline modeling
Building per-person physiological models that describe normal variation and detect meaningful departures from it.
- PR03
Multimodal fusion
Combining optical, thermal, acoustic, radar, and environmental measurements into a single coherent representation of state.
- PR04
Closed-loop response
Investigating whether controlled non-invasive stimuli can produce measurable, reproducible physiological change.
Stimulation research
Frequency-based stimulation research
SONA is researching whether precisely controlled acoustic or vibroacoustic stimulation can produce reproducible changes in measurable physiological states.
Conceptual research visualization — not clinical output
